These little constant efforts can save you a lot of time and money in the long run. Here are some maintenance steps to implement in order to keep your best cordless impact wrench up and running for a longer period of time:

Use Appropriate Bits and Sockets

When working with an impact wrench, remember to always use bits and sockets that are compatible with its model. Inappropriate power accessories can cause breakage to your tools that might result in physical injuries for you.

Don’t Be Unnecessarily Rough

Try to avoid dropping or dragging your power tools. Always carry them by their handle and treat them well. Make sure you wrap the cords properly after each use.

Avoid Using Your Impact Wrench If It Is Damaged

Make sure to check all the parts of your impact wrench before you use it. In case your power tool appears to be damaged, then repair or replace it immediately.

Clean Regularly

Clean the accessories and every little part of your impact wrench regularly. This will ensure a longer lifespan and improved performance.

Having said that, do not expose your power tool to wet conditions or scorching sun. Keep it completely free of dirt and debris.

Lubricate Moving Components

The basic maintenance of any power tool includes lubricating its moving parts regularly in order to ensure smooth performance.

The moving parts of an impact wrench experience a lot of heat and friction. Therefore, lubricate your impact wrench as per the instructions provided in the manufacturer’s manual.

Cordless Impact Wrenches – FAQ

What size impact wrench do I need to remove lug nuts?

remove lug nuts

Removing old wheel nuts and adding new ones is a common job when it comes to vehicle upgrading and maintenance.

For this purpose you need an impact wrench of a size that is appropriate for the job. You can either go with a 3/8-inch impact wrench or a 1/2-inch one.

These two sizes are ideal for delivering the power needed to tackle tough wheel nuts. Moreover, they don’t apply excessive torque.

Can you use an impact wrench as an impact driver?

The names of these two power tools are quite similar to each other; however, you shouldn’t assume that they’re the same. While there are certainly several similarities between the two, there are some major key differences.

Impact Driver

An impact driver also known as an impact drill is a tool that is capable exerting high rotational torque and forward thrust when it is struck on the back using a hammer.

This tool is ideal for both professionals and amateurs. It is used to drive as well as remove fasteners and screws into and from different materials.

Additionally, the impact drivers are also used to drill holes in hard, tough materials.

Impact Wrench

An impact wrench or impact gun is a power tool that is used to drive fasteners and wheel nuts that demand an extremely high rotational force.

It is used to either tighten or remove fasteners, bolts and screws. Some impact wrenches are powered by compressed air, while others are powered by electricity.

The electric ones are either cordless and battery-powered or corded.

The Key Difference between Impact Wrenches and Impact Drivers

attachment for impact wrench

Even though both the tools have a similar appearance, they have a major key difference.

Impact wrenches and impact drivers both are used in different settings. Impact wrenches are utilized for professional projects due to the high power and performance they deliver.

Impact drivers on the other hand are used in various carpentry, home-improvement and DIY projects. Impact wrenches deliver about 7 times the amount of power that impact drivers do.

How many foot-pounds of torque do I need for tire lug nuts?

Lug nuts or wheel nuts are usually tapered to ensure wheel security and are manufactured to match the thread size of car studs.

Therefore, it is essential to torque the wheel nuts of your car to proper specification in order to ensure proper function and safety of your car.

Read the Manufacturer’s Manual

Read the manufacturer’s manual of your car to learn the specification for torquing wheel nuts. Remember to always follow that specification.

If you can’t find this piece of information, ask a car dealer that sells the car brand you own. You can also contact an auto shop for the purpose.

Notice Torquing Patterns

It is important to torque the wheel nuts of your car in a star pattern. You can start with the bottom right, move towards the top left and so on. This helps secure your car wheel and also prevents it from tilting.

Torquing

Torquing of wheel nuts is expressed in foot-pounds. You can use torque sticks with your impact wrench in order to achieve the correct amount of torque.

If your lug nuts or studs are sized:

  • 7 / 16 inch or between 12 X 1.25 mm to 1.5 mm then your need to torque the wheel nuts to 70 – 80 ft-lbs
  • between 14 X 1.25 mm to 1.5 mm then your need to torque the wheel nuts to 85 – 90 ft-lbs
  • 1 / 2 inch then your need to torque the wheel nuts to 75 – 85 ft-lbs
  • 9/ 16 inch then your need to torque the wheel nuts to 135 – 145 ft-lbs00:2802:08

Can you use normal sockets on an impact wrench?

car maintenance with impact wrench

A straightforward answer to this question is no, you shouldn’t use a normal socket with an impact wrench.

The two main differences between impact sockets and standard sockets are their material hardness and wall thickness.

Both the sockets are typically manufactured using similar type of steel. However, unlike normal sockets, the impact ones are heat treated in order to lower their hardness.

Lower hardness impact sockets are more ductile relatively and they can prevent your impact wrenches from excessive wear.

Moreover, they dissipate forces in a better manner. This causes impact wrenches to last longer and reduces their chances of failing.

The diameter of an impact socket is slightly larger to compensate for the lower hardness and increase the wall thickness.

This allows the impact sockets to reduce the effects of high stresses on themselves when they are being used in conjunction with impact wrenches.

A standard socket might break or crack when used on an impact power tool because of its brittle material. Contrary to common belief, the momentary shock is the main factor that causes damage to the socket rather than the applied torque.

If your socket is located in a confined space like a wheel opening, the wheel may become subject to most of the damage if the socket breaks or cracks.

In result, the socket might come apart and you can become target to serious injuries and wounds from flying shrapnel.

In conclusion, stick with an impact socket to stay safe and secure when using an impact wrench.

Will impact wrench break bolts?

impact wrench for change flat tire

An impact wrench with excessive torque for a particular bolt size can break the bolt, strip the nut or cause it to come loose.

If you are using extremely rusted bolts, they are more likely to break and should be replaced right away.

Conclusion

We understand that nothing is more frustrating than rusted bolts. Impact wrenches provide you with enough torque to move those stubborn bolts and prevent yourself from any potential injuries.

We have mentioned our top picks for the best cordless impact wrenches available on the online market in our guide. These top choices are powerful enough to execute the job you expect them to while offering you value for your money.

With all the aforementioned options, we hope you found something worth investing your time and money in!
